MX-5 Miata NA/NB ME442 Plug-In ECU

Elevate your Mazda MX-5/Miata’s performance with the ME442 MX-5 Plug-In ECU, the latest Engine Management System designed for NA/NB models from 1989-1995. This package includes the Wideband Sensor and Cable for comprehensive engine management.

• Seamless Integration: Designed to replace the original circuit board within the factory ECU casing, retaining the original connector for a straightforward, no-fuss installation. Fits perfectly inside the OEM casing for a clean, factory-like appearance.
• Enhanced Performance: Experience improved engine performance and customization without the need for extensive rewiring or modifying the wiring harness.
• Wide Compatibility: Supports both 1.6 and 1.8 models using the same hardware. The only additional requirement is running a MAP vacuum hose (supplied) from the ECU to the intake manifold.

Along with the standard ME221 feature set, the ME442 version adds the following features:

• On-board Bosch Wideband Lambda O2 Controller
• On-board Real-Time-Clock and SD Card Data Logging
• Drive-by-Wire Support (available for some models, please enquire if needed)
• K-Type EGT Input
• Accelerometer and Gyroscope
• CAN Bus for external dashboards and expandability

The core has as standard:

• Powerful Processing: Utilizes the ME221 ECU Core (NXP Automotive Processing Power).
• Comprehensive Sensor Support: Compatible with factory sensors.
• Plug-and-Play: Supports both switched TPS and linear TPS conversions.
• Fuel and Ignition Control: 16×16 Fuel and Ignition Tables with dual table switching and a VE-based fueling algorithm.
• Injector Compatibility: Run any type of high impedance injectors.
• Advanced Engine Management: Features DSP Knock Control, an in-built 60psi MAP sensor, closed-loop boost, lambda, and idle control, and launch control.
• Sequential Fuel Injection: Fully sequential on 1.8 versions.
• User-Friendly Tuning: Comes with the powerful MEITE tuning studio for easy adjustments and regular firmware updates and improvements.
• Pre-Configured Basemaps: Supplied with rolling road certified and developed basemaps for both turbo and NA setups.
• Open Firmware Approach: Flexible firmware/software features for custom setups.

Additional Notes:

• If using a switched-type TPS sensor (fitted to the 1.6 model), it is recommended to install a variable TPS for improved throttle response. The 1.8 model already includes a variable TPS as standard.
• To run without a MAF sensor, an Intake Air Temperature Sensor is required, available in the options list.

Upgrade your MX-5/Miata with the ME442 MX-5 Plug-In ECU and enjoy the pinnacle of engine management technology with enhanced features and seamless integration.
